und the end of the fabric-strip, 12, is drawn from roll and. eppliedtothe ring-core, and the ring-core is then set in rotation, so winding thefnbric-stripvupon it; and as the fabric is so wound on the core, theworkmen, `with hand tools, termed spades, press the fabric in againstthe under side of the ring-core. The tension with which the faibric l2is drawn from the roll l0 may be relied upon. to insure tight windingof: the fabric onthe core, or, if necessary, pressure rollers, appliedby hund or otherwise,may be used 'for rollingl down the fabric us thewinding proceeds.. After u suitable number of layers of the fabric havebeen wound upon the core in this manner (two layers is usuallyconsidered suilicient), the bead-rings l? nre applied in the mannerpreviously described, and the winding of the fabric is continued, 4thefabric beineA now caused to cover the bends. ilue fabric is rolled downover the bends by suitable groovedbeadperfecting rolls, which may beinhand-tools operated by the workmen, or muy be mounted und actuateddescribed. in my prior applications 'for putents,.Sr. Nos. 582,186 und585,623, of each of which applications this present application is adivision. After a suflicient number of these outer layers of fabric havebeen applied, the strip of fabric is cut, its end pressed down tightlyon the layer of fabric beneath, and the Vedges of the febric areAtrimmed by applying suitable trimming knives just beneath the bead; and

these trimming mives may be in hand tools operated by the workmen, ormuy be mounted und actuated as described 1n my said prior applications.One or more layers of gum are then applied to the outer portion of theshoe to form what is termed the pudding This padding usually covers theentire outer surface of thel carcass as so for formed, from the `bend onone side there! of to the bead on the other side thereof. Such loyer orlayers of (rum rnc-y be applied combination n rotatable core, ulpon w byhand, or, and preferubl may be applied by substituting in the mac ine,for thefabrie supply roll l2, another supply roll carrying a gum strip.The gum 1s wound upon the partly formed shoe in the same way as is thefabric, und, usually, is pressed down tightly as so wound, by rollersheld by hund or otherwise against the shoe. Another strip of gum,somewhat narrower, and, usually, considerably thicker than the strip forforming the padding, is then applied to what is to be the tread surfaceof the shoe, in n similar manner. The construction of the shoe is thencomplete, and it is ready for the curing, which latter is done in theordinary manner.

18, in Fig. 3, designates one of the spades,

zZ c., the hand tools usedfin pressing the l fabric against the core.1What I claim 1s:- v V '1. A t1re-form1ng machine comprlslnigv 1n nchthe tire may be formed, a chuck or holding said core, und bead-applyingmeans comprising u circular form adapted t0 hold n circular bend-ringand to be placed adjacent to the core, said form und chuck provided withmeans for centering the form with re spect to the core.

2. A tire-forming'machine comprising in combination a rotatable chuck,a` core held thereby and upon which the tire may be formed, said chuckprovided with n cylindricul shoulder, and a bead-applyingr form adaptedto fit over' seid shoulder in a position in which it isadjacent to saidcore, said form adapted to'hold :t circular bead-ring.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
